Abstract(in Japanese) (See Japanese page)
Abstract(in English) Correlation analyses for neuronal spikes, which have been developed recently, generally give the information on the basic topology of networks as well as the functions of the brain. To analyze the network temporal dynamics, we develop a statistical way on the assumption of probabilistic firing neurons that let through spikes at a certain probability. In this study, we firstly use this assumption on the firing neurons to analyze temporal structure of the network with random connectivity;and, give an explanation of the irregularity of spike sequences generally observed in the cortical neurons. Moreover, considering the spatial structure of a network, we secondly analyze the spatiotemporal interaction of a network with local connectivity. We also discuss the possibility of information processing with the results.
